Why does my smart TV suddenly have no sound?

Samsung TV No Sound - How to Fix (2) Smart TV Edition
August 25, 2023 167 view(s)
Why does my smart TV suddenly have no sound?

 

If you're using one of the latest Samsung Smart TVs, you could encounter an issue when using Bluetooth Transmitters or Headphones. The issue is due to the fact that Samsung Smart TVs tend to pair with any Bluetooth devices it can find unless you manually deny the connection. 

 

This could lead to odd behaviors on your Samsung TV such as no picture, Blue / Black Screen with an error message, TV headphones and base not reconnecting, no sound on TV headphones, transmitter cannot pair to headphones, etc. 

 

Bear in mind when using Samsung Smart TVs: 

1. If your headphones / transmitters suddenly stopped working with your TV, it may be because your Smart TV performed an automatic update and reset all of its settings to its original form. Smart TVs also do automatic updates because they are connected to your Wi-Fi, just like a computer. Even though you didn't do anything, the TV changed itself. In these cases, follow the steps from the beginning to troubleshoot the issue.

2. The TV remote control does NOT turn TV off. It only puts the TV into standby mode. The TV will still perform its "Smart" functions in standby mode. For example, the Samsung TV will still aggresively connect to all devices it finds. The best way to turn the TV OFF is to physically switch it OFF or to pull the plug.

Here is the FIX for the above issue with Avantree TV headphones and transmitters.

 

1. REMOVE / DENY the Avantree Device from Samsung TV's "External Device List."

2. Keep the TV OFF (Not in Standby) if you have any issues reconnecting the headphones and the base. 

 

DENY the Device:

When the Samsung Smart TV detects your Avantree Device, a popup will appear on the screen, asking you to Allow or Deny the device to connect to the TV. You MUST DENY the device from connecting, otherwise it will not be able to connect with the other device in its set.

 

 

REMOVE the Device:

If you did allow the device to connect to your TV, or if your device connected to your TV automatically, you will need to remove the device from within your TV's settings.

Settings >> General >> External Device Manager >> Device Connection Manager >> Device list - >> Edit >> Select all Avantree Device >> Delete

 

 

After removing / denying the Avantree device from the Samsung TV's external device list, your Avantree devices should work properly now. If not, you might need to re-pair & lock the headphones with the base again. Here is how to do it:

 

1. Turn OFF your Samsung Smart TV. Either flip the physical switch on the TV, or pull the plug from power. If you cannot physically turn OFF your TV, an alternate method to try is to press and hold the power button on your TV remote for 6 seconds until the TV turns off.

2. Turn on your Headphones and Transmitter. It is recommended to have your transmitter plugged into a wall outlet, not your TV, as the TV should be off at this point.

3. Get the Headphones and Transmitter into pairing mode (rapidly flashing RED & BLUE). For more information, please refer to your devices' user manual or support site. 

4. If your Headphones and Transmitter have a LOCK function, please LOCK the headphones and the transmitter together. For more information, please refer to your devices' user manual or support site.

 

Now, the headphones and transmitter will be locked together, so that the next time you use them they should automatically re-connect with each other and show solid BLUE on the headphone. NO need to re-pair them each time.

If this does not fix it, pls contact support@avantree.com.
